Spring错误创建名为'org.springframework.aop.config.internalAutoProxyCreator

Question

我正在尝试为Spring AOP执行一个简单的程序。它的代码如下 - ：BusinessService .java

package com.kruders.spring.aop;

public interface BusinessService {
    void doSomeThing();
}

BusinessImpl.java

package com.kruders.spring.aop;

import org.springframework.stereotype.Service;

public class BusinessImpl implements BusinessService {
    public void doSomeThing() {
        System.out.println("Do Something Here");
    }
}

BusinessAspect.java

package com.kruders.spring.aspect;

import org.aspectj.lang.ProceedingJoinPoint;

public class BusinessAspect {
    public void before() {
        System.out.println("Before method is called");
    }

    public void after() {
        System.out.println("After method is called");
    }

    public void afterReturning() {
        System.out.println("After returning method is called");
    }

    public void afterThrowing() {
        System.out.println("After throwing method is called");
    }

    public void around(ProceedingJoinPoint joinPoint) throws Throwable {
        System.out.println("Around method is called");
        System.out.println("Around before is running");
        joinPoint.proceed(); 
        System.out.println("Around after is running");  
    }
}

Main.java

package com.kruders.spring.core;

import org.springframework.context.ApplicationContext;
import org.springframework.context.support.ClassPathXmlApplicationContext;

import com.kruders.spring.aop.BusinessService;

public class Main {
    public static void main(String args[]) {
        ApplicationContext appContext = new ClassPathXmlApplicationContext("Spring-Business.xml");
        BusinessService businessService = (BusinessService)appContext.getBean("businessService");
        businessService.doSomeThing();
    }
}

弹簧Business.xml

                    pointcut-ref="businessExp"/>
       </aop:aspect>
    </aop:config>
</beans>

我已经包含了所有的AOP罐子并使用了spring-4.3.6

Spring Aop Jars-:

aspectj-1.6.9,aspectj-DEVELOPMENT-20160512153500,aspectjrt,aspectj-weaver,spring-aop jars 

但仍然出错。

看起来这是一个类路径问题。正如here所述，aspectj和spring-aop罐之间存在一些冲突。

已将您的项目移植到maven项目，下面是pom.xml

        </dependency>

        <!-- https://mvnrepository.com/artifact/org.springframework/spring-aop -->

            <version>4.2.6.RELEASE</version>
        </dependency>


    </dependencies>
</project>

同样在Main class中，

ApplicationContext appContext = new ClassPathXmlApplicationContext("Spring-Business.xml");

发出警告说appContext未关闭。 appContext是执行一些I / O操作的ResourceLoader，在执行I / O操作后释放资源至关重要。因此，已将其更改为ClassPathXmlApplicationContext，其中.close()方法最终释放资源，您可以更精确地在finally块中执行此操作。

总之，主要方法如下：

ClassPathXmlApplicationContext appContext = new ClassPathXmlApplicationContext(
                "Spring-Business.xml");
        BusinessService businessService = (BusinessService) appContext.getBean("businessService");
        businessService.doSomeThing();
        appContext.close();

希望这有帮助！祝你好运！

aopaplliance-alpha1.jar不包含Advice类，因此为了能够使用它，您必须单独下载aopalliance-1.0.jar文件并将其添加到依赖项中。

包含该文件的一个链接是here。
